can't connect to MSSQL database 2012

I used code snippet in this tutorial to connect to MSSQL darabase.

http://www.java-tips.org/other-api-tips/jdbc/how-to-connect-microsoft-sql-server-using-jdbc.html

but when I run the program, I got this error.

     java.sql.SQLException: Network error IOException: Connection timed out: connect
    at net.sourceforge.jtds.jdbc.ConnectionJDBC2.<init>(ConnectionJDBC2.java:410)

my connection url is 

db.dbConnect(
     "jdbc:jtds:sqlserver://CSLK-PT12DB:1434/R8_JBOSS_MSSQL_Archived_Migrated_Beta","spider3","spider3");
    }

what is the reason for this exception and how to solve it?

I had the same error, and I fixed it by changed SQL Server Express properties. MyComputer > Manage > SQL Server Services > SQL ServerLog on > built -in account > from Network service to Local System.

If nothing is listening, SQL Server isn't accepting TCP connections. You'll have to configure SQL Server to do so. This article explains how to enable a server network protocol for a given instance.
